Industrial immersion heaters are designed to heat up fluids and gases, usually stored in tanks, and are submerged directly into the substance they are intended to heat.
Industrial Immersion Heater Applications
Immersion heaters are essential components in a wide range of manufacturing processes, such as oil refining, chemical processing, food and beverage production, and many more.
These heaters come in a variety of shapes and sizes, including flanged, screw-plug, and over-the-side immersion heaters. Flanged immersion heaters are installed in tanks or vessels through a flange, while screw-plug immersion heaters are screwed directly into the tank's opening. Over-the-side immersion heaters are suspended over the tank's opening and immersed into the liquid.

How do Industrial Immersion Heaters Work?
Industrial immersion heaters work on the principle of Joule heating, which involves passing an electrical current through a resistor to generate heat. In immersion heaters, the resistor is a high-resistance heating element made of metal or alloy. When the current passes through the heating element, it generates heat, which is transferred to the liquid or gas surrounding it, resulting in the temperature rise of the substance.
The heating element's sheath material is critical to an immersion heater's efficiency and effectiveness. The most common materials used in industrial immersion heaters include Incoloy, copper, and stainless steel (304 or 316). The sheath material used in the heating element depends on the type of fluid being heated, the temperature range required, and the heater's lifespan.

Why are Industrial Immersion Heaters Important?
Industrial immersion heaters are essential in various manufacturing processes. They provide a reliable and efficient method of heating liquids and gases to the desired temperature, ensuring that the manufacturing process is completed efficiently and effectively. Immersion heaters are used in numerous applications, such as oil and gas refineries, chemical processing, food and beverage production, water treatment plants, and many more.
In the food and beverage industry, immersion heaters are used to heat liquids such as milk, syrup, and chocolate. In the chemical industry, immersion heaters are used to heat acids, solvents, and other chemicals. In the oil and gas industry, immersion heaters are used to heat crude oil, which makes it easier to transport.

Watt Density
Watt density is a critical parameter in industrial immersion heaters. It refers to the amount of power dissipated by the heating element per unit area of the heater's surface area. It is typically measured in watts per square inch (W/in²). The watt density of an immersion heater is a crucial factor that determines its efficiency, lifespan, and effectiveness in heating the target substance. Here are some of the reasons why watt density is important in an immersion heater:
Efficiency: The watt density of an immersion heater is directly related to its efficiency. A heater with a high watt density will heat up the target substance faster than one with a low watt density. However, a high watt density also means that the heating element will generate more heat, which can result in premature failure due to overheating. Therefore, the watt density should be optimized to achieve the best balance between heating rate and lifespan.
Lifespan: The watt density of an immersion heater is closely related to its lifespan. A heater with a low watt density will generally last longer than one with a high watt density. This is because the heating element in a high watt density heater is exposed to more heat, which can cause it to degrade more quickly. Therefore, it is essential to select the appropriate watt density for the application to ensure a long lifespan for the heater.
Safety: The watt density of an immersion heater also plays a crucial role in ensuring safety. A heater with a high watt density can produce too much heat and create hot spots, which can lead to overheating and even a fire. Therefore, it is crucial to select the appropriate watt density to avoid such hazards.
Target substance: The watt density of an immersion heater also depends on the substance being heated. The target substance's thermal conductivity, viscosity, and specific heat capacity determine the heater's watt density required to achieve the desired temperature. For instance, liquids with high thermal conductivity and low viscosity require a lower watt density than those with low thermal conductivity and high viscosity.
